MathML entity references support in DITA 1.3

[Radu Coravu <radu_coravu@sync.ro>]

Hi,

We've had two companies so far which want to use DITA 1.3 because of the 
default MathML support but they also want to use entity references in 
the MathML content.
The MathML DTDs have a rich set of entity definitions but the decision 
seems to have been to remove the possibility of using those entities 
when MathML is embedded in DITA content.
Could this be reconsidered? The specification does not seem to state 
that the MathML which can be embedded by default in DITA cannot use 
entity references.
So maybe the MathML DTDs bundled with the DITA 1.3 standard could be 
just edited to remove this limitation.
The "mathml3-ditadriver.dtd" explicitly ignores these entities by 
redefining a certain parameter entity:

> <!ENTITY % mathml-charent.module "IGNORE" >

Regards,
Radu
